The M-601C is commercially rugged and suitable for outdoor installations. M-601C - AM Active Antenna Price: $189.00 The loop antenna and receiver may be hand held or mast mounted.ġ0 kHz to 500 kHz +/-3 dB (normalized loop response)Ģ4" square / 12" handle, 1.5 lb, PVC frame The 24 inch square PVC loop may be broken down into components for storage. The design consists of a balanced peaked lowpass coaxial design providing exceptional sensitivity and directivity.įrequency response is 10 kHz to 500 kHz (broadband). The LF active broadband coaxial wound loop is used in conjunction with an LF receiver input circuit. L-950 - LF Active Loop Antenna Price: $460.00 The L-400B broadband filter design enables you to effectively receive the entire LF spectrum from 40 dB above 600 kHz The versatile and proven reliable L-400B may be used with all 50 to 100 ohm input receivers and converters. The L-400B active antenna is a compact 26 inch fully sealed e-probe designed for receiving within the VLF and LF spectrum. L-400B - LF/VLF Active Antenna Price: $210.00 An internal voltage regulator provides better than +/- 1Hz frequency stability.Īntenna probe tested to 2 atmospheres (-66 ft)ġ20 VAC / 12 VDC power pack with 2.5 mm plug Supplied with fifty feet of RG-174/U cable. Receiver tuning is between 4.0 MHz and 4.5 MHz. rejection greatly improves reception below 10 kHz and its sharp roll-off filter characteristics eliminate BC intermodulation. The externally mounted LF converter contains a low impedance wide dynamic range balanced mixer, with RF, IF and local oscillator filtering. The L-111 combines the proven L-400B active antenna with a sensitive LF to HF converter.

The L-111 System provides full coverage of the LF spectrum from less than 10 kHz to 530 kHz. L-111S - LF/VLF Converter/Antenna System Price: $269.00 Tape recorder/sound card and earphone outputs included with the ELF receiver.ģ00 Hz to 30 kHz flat response +/-3dB (zero impedance amplifier) (system sensitivity 375 mV/V/m)ġ.5 kHz (highpass, single pole) in HP modeĩ volt, 7 – 10 mA typical, 100mA full audio outputĢ4 inch square / 12” handle, 1.5 lb (PVC pipe) Switchable high pass filter for noise reduction. The loop antenna and receiver may be hand held or tripod mounted.
Frequency response is 300 Hz to 30 kHz (broadband). The directional loop design in combination with the receiver's high pass filtering, greatly reduces unwanted noise and hum. The L-600S is an effective H-Field receiving system for use in EMI noisy areas, or within E-field attenuated areas. Quantity: The L-600S is designed with the serious experimenter in mind. L-600S - H-Field Loop Receiving System Price: $480.00
